HEATING AND VENTILATING- REGISTER.

The present invention relates to heating and ventilating registers and more particularly to the type in which the register is provided with a shutter for controlling the flow of air through the same; An object of this invention is to provide a construction in which the shutter may be controlled through pressure on two separate devices, one effecting the opening of the shutter and the other effecting the closing of the shutter. Still another object of the invention is to provide operating means for the shutter controllable through two plungers, one effecting the opening of the shutter and the other effecting the closing of the shutter. Still another object of the invention is to provide for constructing the side walls from a single strip of material, provision being made whereby the shutter may be assembled within the wall after the latter has been formed. A further object of the invention is to provide a novel means of securing the pivots or pintles of the blades to the side walls.

To these and other ends, the invention consists of certain part and combinations of parts, all of which will be hereinafter described: the novel features being pointed out in the appended claims.

Referring more particularly to the embodiment of the invention herein illustrated, 1 indicates a face plate provided with openings 2 through which the air may pass. Projecting from the rear face of this plate are the side walls 3 of the register. These Application filed October 28, 1924. Serial No. 746,446.

side walls, in this instance, are formed from a single piece of sheet metal bent into rec tangular form and having their ends secured together by rivets 4. Each side wall has an outwardly extending flange 5 at one edge secured by rivets 5 to the face plate 1. Two walls 3 are narrower than the other two side walls and one of these narrower walls is narrower than the other, but both are provided with inwardly turned flanges 6 at their outer edges. The other two side walls support the shafts 7 and the blades 8 of the shutter. In this instance, three of such blades are provided and each is formed from sheet metal with one edge 9 deflected slightly to one side of the planethereof, so that all blades may lie in overlapping relation and in the same plane. The outermost edge of one of the blades 8 cooperates with the outer face of the flange 6 of the narrower of'the two narrow walls while the deflected edge 9 of the otheroutermost blade cooperates with the inner face of the. flange 6 of the wider of the two narrow walls 3, so that when the shutter is closed a substan tial air-tight passage is provided. In order to secure the blades 8 to their shafts 7,

each blade has a longitudinally extending depression 1.0 in which the rod 7 is secured, the rod being flattened at 11 and secured to the blade by a rivet 12. In this way the turning axis of the rod 7 is substantially in the plane of the blade.

To the end. that the rod 7 may be secured to the side walls after the latter has been bent into rectangular arrangement and secured together by the rivets 5 the two wider side walls 3 are provided with notches or recesses 13 which extend to the outer edge of the edges of said side walls, and the rods 7 are formed with annular grooves 14:.

providing reduced portions on said rods, the

diameters of these reduced portions being substantially equal to the width of the notches or recesses 13 so that the side walls 3 about the notches or grooves will cooperate with the walls of the annular grooves or notches l l and prevent the longitudinal movement of the shafts 7.

lVith the end in view of holding the shafts in the notches or recesses 13, retaining devices 15 may be employed, one for each end of each shaft. These retaining devices, in this instance, are formed from small pieces of sheet metal bent into channeled or U- shaped cross sectioin Each side of the chem eter on the shaft.

neled or U shaped member is recessed Q1 notched at 16, the notches or recesses in the two sides being aligned and having a width substantially equal to the diameter of the reduced portion 14: of the shaft 7. The U shaped member is fitted over the edge of the side wall adjacent the notch 13 so that the ends of the notches 16 form withthe end of the notch 13 a circular opening, the diameter of which is substantially equal to the diameterof the reduced portion of the diam- The U shaped holding clips or devices 15 may be held to the. side walls in any suitable manner. In this instance, the side walls are formed with recesses or seats 17, the length of each of which is equal to the length of the clip and from each seat on opposite sides of a. recess 13 two projections '18 extends The connecting portion of the two arms of each holding clip or fastener 15 is provided with two openings or recesses 19 and when the holding clip or fastener is arranged on a seat 17 the projections 18 will extend through the openings 19. These projections are then flattened or upset so as to overhang the walls of the openings 19 in the ,clipor'holding device, and in this way retain such clip or holding device in position.

For effecting the simultaneous movement of the shutter blades each blade has at one end a lip or arm 30 turned laterally therefrom and to this lip or arm, a connecting bar 31 is pivoted at 32, this connecting bar being common to all of the blades sothat motion imparted to one of the blades is transmitted to the other two.

The operating mechanism for the shutter embodies, in this instance, a channeled member 20 rigidly secured to the central rod or shaft 7 so that its channel extends atright angles to the axis of the rod and at oblique angle to the plane of the blade. WVith the bottom of this channel thetwo ends of levers 21 and 22 engage, the former of these levers being pivoted at 23 to the end wall 8 adjacent the channeled member 20 and the other being pivoted at 2 k to said wall, the pivots 23 and 24 being arranged adjacent the ends of the end wall to which they are secured and the levers extending inwardly from said pivots toward each other and cooperating with the bottom of the channeled member 20. In order that the levers 21 and 22 may be held to the channeled member each lever has a lateral projection 28 at its free end which operates in a slot 29 inthe side wall of the channel member 20 and holds the lever to the channeled member. Each lever has extending laterally from the plane thereof to one side of but adjacent to its pivot an arm orprojection 25 and with this arm or projection 25, a slide or plunger 26 engages.

These plunger-s are mounted on the face plate, so as to project beyond the outer face position of the shutter, vill when its plunger 26 is depressed act on the channel member 20 in a direction to turn the blades from the position which they occupy to the opposite position, thereby shifting the channel member and carrying the free end of the end of the other lever toward the face plate in order that the latter lever may next'be employed for shifting the blades.

From the foregoing it will be seen that there has been provided, a register for heating or ventilating purposes in which the shutter isoperable through two pressure de vices, oneof which effects the movement of the shutter in one direction and the other effects the movement of the shutter in the other direction. These pressure devices are in the form of plungers which have a novel connection withfthe shutter blades. This connection, in this instance, embodies two levers extending toward each other and a shifting device rigidly secured to one of the blades,.the shifting device preferably being in the form of a guiding means on a channelled block arranged transversely of the axis of turning ofthe-blade and at an oblique angle to the plane of the blades, and engaged by the ends'of the two levers. The shaftsof the blades are secured to the side walls of the register by novel retaining devices which permit the blades to be assembled on the walls after the latter have been arranged in rectangular formation, and secured together by the rivets.

What I claim as my invention anddesire to secure by Letters Patent is:

1. The combination-with a frame and a shutter. for closing/the opening through the frame, of an oscillatory shifting device hav- T ing guiding portions on opposite sides of the center of turningof said devices and connected with the shutter to effect the opening of the shutter when said shifting device is moved in one direction and to effect the closing of the shutter when said shifting device is moved in the opposite direction, and two levers each pivoted at one end and having its other end operating on the guiding portions of the shifting device on oppositesides of-the turning center of the latter, so that pressure on the levers alternately will move the shutter in opposite directions.

2. The combinationwithQa frame and a shutter for closing the opening through the frame, of controlling meansv for the shutter embodying two plungers, an oscillatory shifting device connected to the shutter so that movement-of said device in one direction effectsthe opening of the shutter and movement in the opposite direction efiects the closing of the shutter, and two levers, each engaged by one of the plungers and 00- operating with the shifting device on the side of the pivot of the latter opposite that engaged by the other lever.

3. The combination with a frame and a shutter for closing the opening through the frame, of an oscillatory shifting device connected with the shutter and having guiding portions on opposite sides of the center of turning thereof, and two levers extending toward each other from their pivots and engaging the guiding portions on the oscillatory shifting device on opposite sides of the turning center of said device so that alternate pressure 011 the levers will move the shutter in opposite directions.

4. A register comprising a register frame, side walls secured to the register frame and having their free edges extending outwardly and formed with outwardly disposed notches, shutter blades for closing the open ing through the register having shafts fitting in the notches, and clips secured to said 2 Walls and holding the shafts in the notches, said clips being of channel formation and straddling the walls over the notches.

5. A register comprising a register frame, side walls secured to the register 3 frame, two of said walls opposite each other, each being formed With a notch in its free edge, a shutter blade having a shaft fitted in the notches of the two walls, and clips secured to both walls and holding the shaft 3 in the notches, said clips being of channel formation and straddling the walls and each having an opening in the bottom of its channel, and the walls having lugs extending through said openings and upset over the 4 clips.
